There are a lot of non-ubuntu questions that are off-topic but not unix questions. That should also be an option in the off-topic flag dialogue.

Questions on Linux or Unix which don't involve Ubuntu are off-topic here, but can be asked on Unix & Linux Stack Exchange. For questions on Windows and Mac OS or any other operating system, please contact their respective official support centers or try Super User or Ask Different.

End Of Life proposal:

We have many EOL questions, currently considered off-topic. So I propose we have a custom off-topic reason for them, we should include a link to a question that shows them how to update Ubuntu - Possibly a link to the EOL date list for when versions are no longer supported (maybe even the question that tells them how to add archived repositories)
